Guild Wars 2

i can’t sell it on the trading post for some reason and my pile of incandescent dust i have 250 in my bank of both

Are you trying to sell directly from your bank slots? For me, I cannot sell from my bank slots directly, but if I move the item from my bank to my inventory, I can then sell using right click.

Maybe you have equipped a invisible bag. If you put your Orichalcum ore and Dust in this bag, then you will be able to right click and sell them at trading post, however you won’t see them once the trading post screen is there. Solution is to just move them to a bag that shows them in the trading post window. And just like mmmpie.4769 said, you can’t directly sell from your bank tab.
